A structural formula for an organic compound that depicts each valence bond as a short line especially : the hexagonal ring formula for benzene
Answer:
Solvent will be lost as gas and not return into the vessel via condensation.
Explanation:
Reflux is a technique used in chemistry to boil a particular solvent and convert the gas formed back into liquid by condensation. This technique allows a solvent to be heated at a regulated temperature but for a prolonged period of time than it would normally take place.
The reflux procedure makes use of a reflux CONDENSER, which is an apparatus that allows vapour from the heating/boiling to flow back into the reaction vessel. The CONDENSER functions to prevent the loss of the SOLVENT as vapour by providing a cooling effect on the vapour.
Therefore, if a reaction was refluxed without a condenser, THE SOLVENT WILL BE LOST AS VAPOUR
When cobalt (II) hydroxide dissolves, it dissociates into the following ions,
Co(OH)₂ --> Co²⁺ + 2OH⁻
molar solubility is the number of moles that are dissolved in 1 L of solution.
If molar solubility of Co(OH)₂ is X, then molar solubility of Co²⁺ is X and molar solubility of OH⁻ is 2X.
the formula for solubility product constant - ksp is as follows;
ksp = [Co²⁺][OH⁻]²
ksp = (X) * (2X)²
ksp = 4X³
ksp = 5.92 x 10⁻¹⁵
4X³ = 5.92 x 10⁻¹⁵
X = 1.14 x 10⁻⁵ M
molar solubility of Co(OH)₂ is 1.14 x 10⁻⁵ M
solubility of compound - 1.14 x 10⁻⁵ mol/L x 93 g/mol = 1.06 x 10⁻³ g/L

As temperature decreases, rate decreases.
As temp increases, k also increases. </span>
